I've done some testing with random numbers with exponents from 10^5 to
2*10^5. What I see is that about 4-5% of the time the fast conversion
is off by one bit from the exact conversion. Can't seem to make it any
The exponent threshold at which the fast conversion is used is
programmable, so perhaps this 5% difference for large enough exponents
